Endometrial Carcinomae (EC) usually occurs at after their thirties. A patient with stage IV EC usually shows short life expectancy. Here, we describe a unique stage IV EC patient, unique in that 1) she was 23 years old and 2) she survived 8 years. A 23-year old woman had heavy bleeding and the condition was diagnosed as uterine myoma: myomectomy was performed; during the surgery bloody ascites was noted and histological examination of resected uterine tissue (initially considered as myoma) revealed EC. Diagnosing this condition as EC, after informed consent, total abdominal hysterectomy with bilateral salpingo-oophorectomy with omentectomy was performed. Also, intra-surgical examination revealed the presence of sub-diaphragmatic metastatic lesion, which was resected. Reduction surgery was successfully performed; however, the cancer recurred, to which chemotherapy and irradiation was performed; she died after 8 years. We did not save her life; however, she lived 8 years in self-dependent manner.
